Crower 66264-16 Features:

CNC-machined billet alloy body with a raised heavy-duty blade for Holden LS V8 and 2S Series early-model V8 applications; sold as a set of 16. Standard .8415 in. lifter body diameter fits .842 in. lifter bore blocks, with a .9031 in. pushrod seat height for correct valvetrain geometry. Crowned bearings and a crowned outer race help reduce lobe tracking, while control-contoured tapered needle bearings support high cylinder pressure and high rpm use. Captive blades use Crower’s orbit-formed locking mechanism to permanently attach the spool, eliminating snap rings that can loosen in severe-duty operation.
